EFL university teachers' emotions are likely to be influenced by students’ behaviours in the classroom. Thus, practicing emotion regulation is considered to support teachers to achieve their professional objectives and effective teaching. In this case study, the negative emotions associated with classroom teaching experienced by an EFL university lecturer due to students’ behaviors were video recorded.
